The Novy Temir Fe occurrence with magnetite ores and copper mineralization is confned to the central part of the Kulikovsky serpentinite massif. Copper was mined here ig the Bronze and Early Iron ages. The primary Cu minerals are chalcopyrite and bornite. The secondary Cu minerals in oxidation zone include malachite, chrysocolla, azurite, and rare delafossite, covellite and chalcocite. In addition to copper minerals, the ores contain Ni and Co sulfdes, arsenides and sulfarsenides (pentlandite, nickeline, cobaltite, unidentifed Ni arsenide). The Ni, As and Co minerals in oxidation zone are rare, which is related to their rare primary occurrence.
